Application filed December 31', lead Serial No. 434,352.

v Thisinvention relates'to an improved repair washer of theltype that isdesigned to be placed on a shaft or aide to fill or partially fill the space between end-bearings caused by wearing of parts so asi to cause or permit unnecessary play lpngitudinally of the shaft-or axle, the invention having. reference more particularly t a washerthatus .adapted to be r adily applied to a machlnery shaft or axle without itbeing necessary to transport .theniacliineryto a work shop or'to remove the shaft or from its place in the machinery.

H An object .of the invention is to provide 11 an improved machinery repair washer ofthe above-mentioned-cliaracter thatshall be so constructed as to be adapted to be readily placed on a rot-aryshaft .or agile to take up or reduce longitudinal motion ,of the shaft in-its bearings, moreparticuarly where a solid washer cannotbeslipped over an end of a shaft to-the shaftfbearingj i i Another object isto provide an improved sectional repair .Wa sher which shall. be so constructed as to ,bel adapted to closely embrace the shaft or axle on which it may, be needed, and which shall have improvedlocking ineans to secure the sections ofitlie washer together of such type as will. permit practical operation thereof in casethe washer must be of large dimensions and when the metal thereof can have only a little or no elasticity necessary to snap-locks.

A further object is to provide an imroved machinery repair washer having inged sections adapted to be securely and permanently locked together in place and by simple boltless means; which Washer may be produced at small cost and be durable and economical in use. 7

With the abovementioned and other objects in view, the invention consists in an improved sectional machinery repair washer having novel means for locking the sections thereof, together; and, the invention consists also further in the parts and combinations and arrangements of parts or features as hereinafter particularly described and further set forth in the accompanying claim.

Referring to the drawings,-Figure 1 is a plan view of the improved washer as produced in condition to be applied for use; Fig.2 is a fragmentary plan View of one of the sections of the washer; Fig. 3 is a fragmentary plan view of the companion section ofthe washer; l isa plan View of the washer having thesections thereof lockedtogether'as when in use; Fig. 5 is a fragmentary. detail showing a small car wheel and? axle supporting a portion of'a car frame, to which the improved asher is applied as illustratingone of th e pun posesai d function of the invention. Similar reference characters in the differc l t. figures of the drawings indicate corlfespond'ing elements or features. of constructijon'herein referred to in detaiLi v I r The improved washer-aspreferabdy constructs comprises two sections an d 2'01 semi-. r ular contour, the'isections being of uniform" thickness thr o'llghout excepting they have relatively thinihinge portions 3. 4 respectively one, end the'reof, the hinge portions being" arranged in over-lap Qi'ng I relation and connected together by a suitable pivo t 5. if The sections n rtsjof the, washer have concavely-curved inner edges .6 and {respectively thata're earl; coeg ztenslve w th one-half of a circle; and the sect ons; have, also con. ly curved per pheral portionsor edges 8 and 9 respectively.

.Qne of the sections L has an extension; or tongue 10 that adiap'ted tobe locked tothe companion section, andwhen produced and ready to be locked tof t heother section the tongue projects from the body portion of a section tangentially" and preferably has a curved outer edge 11 that corresponds to the [curvature of the edge 8, so that When the tongue is loched to the companion section the edge will constitute a continuation S" of the edges 8 and 9. The sections are composed of suitable metal, such as tough and flexible brass or other anti-friction metal that will permit of the tongue being bent slightly to effect locking arrangement of the sections. The washer is usually of substantial thickness and large diameter, particularly when required on small car axles commonly used at mines.

More specifically the body portion of each section corresponds in extent circumferentially to onehalf circle, so that one section has a squared end portion or shoulder 12 beyond which the tongue 10 extends from the body portion adjacent to the periphery thereof. The companion section is of re duced width adjacent to its locking end so as to have a relatively narrow but yet solid anvil portion 13 which has a squared end 14 to abut against th end portion 12. The portion 13 has an outer edge 15 at approximately right angles to the end 1 1 and extending a suitable distance from the end, and has also a recess 16 at one end of which is a locking shoulder 17, the opposite end of the recess having an oblique angled end 18 extending from thebottom of the recess to the edge 9. The tongue 10 when not locked to the companion section has an inner edge or recess 19 extending at an obtuse angle from the outer end 20 of the portion 12, and beyond the recess the tongue has an inwardly extending portion 21 to enter the recess 16 and to form a locking shoulder 22 facing toward the end portion 12 to en gage the shoulder 17 when the tongue is bent inward, the edge or recess bottom 19 after the tongue is bent representing an inner edge 19 that extends at right angles from the end portion 12 against the edge 1.5. The tongue has an angular end 28 corresponding to the end portion 18.

In Fig. 5 the numeral 2st indicates a portion of a car frame having a journal box 25 supported on an axle 26 mounted in a wheel 27 having a hub 28 facing the journal box to prevent movement of the journal box along the axle, and the improved washer is shown on the axle between the journal box and the wheel hub to compensate for wear and prevent undesirable movement of the car body longitudinally of th axle.

In practical use, a repair washer of the required thickness to freely enter the space it is to occupy is selected from a stock of washers assumed to be kept on hand. The sections of the washer are swung apart on their hinge connection to permit the free ends to pass over the axle or shaft transversely thereof, and the sections are freely brought together until they embrace the axle or shaft, the locking portions of the sections then appearing as in Fig. 1. The anvil portion 13 of one section being against the axle and the base portion 20 of the tongue being against the end of the edge 15, the edge 11 of the tongue is struck by a hammer or other instrument and the tongue is bent inward until the locking shoulder 22 engages the shoulder 17, with the edge 21 in the recess 16, the washer bein then securely locked in place. 'lVhen lost motion again develops the hinge connection prevents lateral displacement of the locked portions until another washer of suitable thickness may be similarly applied to the axle or shaft against or in lieu of the washer previously applied.

daving thus described the invention, what is claimed as new is- In a machinery repair washer, the combination of a washer segment having at one end thereof a solid anvil portion squared atits end and of less width radially than the body portion of the segment, the-outer edge of the anvil portion having a locking shoulder, a pivot connected to the segment at the opposite end thereof, and a washer segment connected at one end thereof to the pivot and having on its opposite end a tongue projecting from the segment end and having a locking shoulder on its inner edge, saidsegments being composed of flexible anti-friction metal and said tongue having a base portion that is of a width to enable the tongue to be deformed 0n the said anvil portion to cause co-engagement of said shoulders.

In testimony whereof, I afiix my signature.
